Seiko - SPB433J Prospex Black Series ‘Night Vision’ Sumo Diver Limited Edition Watch

A new edition within the Prospex ‘Black Series’ series collection, this ‘Night Vision’ Sumo Diver’s watch depicts underwater night diving views seen through a night scope.

On its grey dial are hands and indices coated with a high strength green ‘Lumibrite Pro’ for added visibility in poor light. The ‘Night Vision’ pieces are the first Seiko watches to feature coloured Lumibrite in green as it is the easiest colour to see in the dark, but also ‘Pro’ because of its higher intensity glow for brighter and longer. Surrounding the sapphire glass is a scratch-proof ceramic bezel, whilst in classic Prospex ‘Sumo’ style, this piece has a strong and bold outer appearance.

Powered by an in-house automatic 6R35 movement, accurate to -15/+25 seconds per day, it has a 70-hour power reserve.

The limited edition issue number is engraved on the case back and it also comes in a special limited edition box.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
